IMPROVED APPARATUS FOR DISCHARGING BlLGE-WATER FROM VESSELS HOLDS.

Spccilication forming part of Letters Patent N0. 58,4 16, dated October 2, 1866.

To all whom t may concern:

Be it known that I, AUGUs'r HERMANN, of

.the city of New Haven and State of Connecticut, have invented a new and useful Apparatus for Freeing Vessels from Water; and .I hereby declare the following to be a full, clear, and exact description thereof, reference heilig had to the annexed drawings, making a part of this specification, in which- Figure l represents a 4bottom view of said apparatus 5 Fig. 2, a cross section thereof through line A B; l"i g. 3, a cross-section there- 0f through C D.

The same letters mark the same parts in all these tigures. f The nature of my inventionconsists in constructing in the bottom or bilge of a ship or vessel a circular-shaped apparatus, with a vertical axle reaching to the deck of the vessel, by the rotation of which apparatus water accumulated in the vessel will be forced out.

To enable others skilled in the art to make and use my invention, l will proceed to describe the same.

In the annexed drawings, E F represent the bottom of a vessel; Gr H, the deck thereof.

I K represent the vertical axis of my apparatus. l

L M N O represent the mantle or casing of said apparatus. One part of said mantle consists of a vertical slide, P, moving in grooves. When the said slide is raised the apparatus is ready for action.

Q is the principal valve of the apparatus, hinged on the upper part of the casing.

. On the axle I K there is permanently fixed a hollow cylinder, R R, which turns with the axle. Said hollow cylinder, on its circumference, has three openings, S S S, communicating, respectively, with'three projecting chambers, T T T,\each of which chambers is provided With a valve, U U U, said valves being so arranged that they will open when the hollow cylinder is turned,and remain closed when the said cylinder is at rest.

When this apparatus is very large, the rotation of the principal axle and cylinder may require considerable force, and then gearingwheels (indicated in Figs. 2 and 3) ma-y be used to rotate the same.

This apparatus is used in the following mauner: When water has accumulated in a ship provided with this apparatus, which is required to be removed, the slide P is raised and the axis I K is put in rapid rotation, whereby the hollow cylinder R R will be also rapidly rotated, and will act, withits projecting chambers T T T, like a centrifugal pump,throwing open the valves U U U, and forcing out the water `through the same, by which the main valve Q will be opened and the water lthere will be forced into the interior of the hollow cylinder, and through it, by means of the valves U U U, to the outside ot' the vessel. When all the water is thus removed from the vessel, the slide P is lowered and the rotation is ceased.

I construct my apparatus of tin, iron, or any other suitable material.

I do not confine myself to the number of chambers attached to the hollow cylinder; but

What I claim as my invention, and desire to secure by Letters Patent, is

The apparatus, substantially as described, consisting of a vertical axle, I K, to which is attached a hollow cylinder, R R, with projecting chambers T T T, containing valves U U U, which open on the said axle and hollow cylinder being rot-ated, said apparatus being operated in the manner substantially as described, for the purpose of freeing vessels from water.

AUGUST HERMANN.
